Premier Loft Ladders recently expanded their range of fire rated loft ladders with the heavy duty Isotec.

The Isotec offers high thermal insulation and superb strength. It also provides fire protection for up to 120 minutes. As such, it is a great solution for a wide range of commercial and residential projects.

To help designers and architects, Premier Loft Ladders has made technical data for the Isotec fire rated loft ladder available within NBS Plus. It can be found within section L30 (clause 421). Also, a CAD drawing is also available.

The Isotec is a folding steel attic ladder rated to 250kg per tread, integrated within an airtight (class 4 certified) and very highly insulated (U-value of 0.33 W/m2K) hatch box. The white powder coated steel ladder features wide treads, measuring (360mm wide by 120mm deep). Also, the Isotec has a handrail and non-slip feet for comfort and safety.

Both the hatch and the ladder itself feature innovative counter-balanced operation. As a result, extending and closing the ladder is particularly easy, which not only improves comfort and convenience, but also has significant safety benefits.

The Isotec loft ladder also offers a standard 30 minutes of fire protection, which can be increased to 120 minutes. This is achieved through the addition of an upper hatch, with further insulation and fire protection.

The Isotec is available in a range of standard sizes or made-to-measure. Standard sizes can also be specified with fully automatic electric operation.
